Isudar Carplay for PCM 3.1
#331
You have to make sure you pick "AUX" as your source...it will always automatically go to CarPlay as soon as you plug it in via USB or whenever it connects via bluetooth. But that doesn't mean it's selected as the source unless AUX is selected. The only way it automatically works is if AUX was the source when you shut down the car.

I cannot push the PCM unit all the way back into place. It sticks 1-2 inches out. I don't want to push hard and break it. What is the trick to stuff all the cables back there?
#334
Yes, you are right, you don’t want to push very hard. But everything should fit. Just arrange wires and harnesses until you can push it back without effort.

I hated it but I had to push it a bit harder. The most nerve wrecking part of the job was inserting the PCM unit back in place.

@torresfe thanks a lot, this worked!!!! Ridiculous how such a simply thing can make everything work. Now it is time to find a way to do the wiring to the back. Next chapter.

So, finally I spent most of the time probably to get the PCM in again. With the extra wiring and mostly the bulky square huge clip (or whatever that is called) I did not manage to get the PCM in. Every timer missed around two centimeters. Finally I found the solution which was to take off the dashboard part as indicated below (tip!!!). Then I fiddled something behind the PCM and was able to wiggle the cables and the huge box a bit so it all fitted. Next challenge is to get the wiring of the rear came to the back. At least I know that everything in the front is fine.

Another question. I read about the software update to manage the volume issues. I am not sure I am understanding this correctly. Does the software update establish that the volume button always controls the correct source that is activitated? So when I have CarPlay on the screen but the radio on it does the radio but when music is running for CarPlay but I am in the normal PCM menu it does the CarPlay? Perhaps somebody is able to explain as if I were a 10 year old? Or direct me to a source that explains this better? Thanks!!!

This is exactly what I was thinking too. I need to move that huge clip out of the way, probably downward to make space for the PCM. I removed that screw yesterday but the piece did not pop out easily. I did not pull too hard yesterday, but I think I will try again today.

NO, that huge clip should not go downwards. If you look into the hole you see at the left mid to top that there is an extra hole of around a few centimeters deep and around 10x10. That is where you want to move the bulky stuff towards and then after a million tries (in my case, also because I was afraid to push hard) it suddenly fits all together. But this is about mini spaces. Good luck!
